Description

Signal transmission and reception method and apparatus

This application claims the priority of a Chinese patent application filed with the Chinese Intellectual Property Office on May 25, 2018, with "Signal Transceiver Method and Device" as the name of the invention. The contents are incorporated into the application by reference and are made a part of this application.

The present invention relates to a communication technology field, and more particularly, to a method and apparatus for transmitting and receiving signals.

OTDOA (Observed Time Difference of Arrival) is a method introduced in 3GPP to use the measured downlink reference signal time difference for positioning. In this method, a user equipment (UE) measures a reference signal sent by a serving cell and an adjacent cell to obtain a value of RSTD (Reference Signal Time Difference Measurement) and reports the RSTD measurement value to the network positioning server. The network positioning server uses a multi-point positioning algorithm or other algorithm to determine the location of the UE.

In order to provide good OTDOA positioning performance, 3GPP specifically defines a PRS (Positioning Reference Signal) for supporting OTDOA so that the UE can detect downlink reference signals from a sufficient number of adjacent cells.

However, while the existing LTE (Long Time Evolution) system does not support multi-beam PRS transmission, support for multi-beam transmission and corresponding beam management is an important function in 5G New Radio (5G NR) and is an important function in 5G NR system. PRS cannot be applied to the terminal positioning.

An embodiment of the present application provides a signal transmission/reception method and apparatus for realizing transmission of a PRS signal in a 5G NR system and further realizing the application of a PRS to a terminal positioning in a 5G NR system.

In the positioning reference signal (PRS) design, the PRS signal of each cell is transmitted in a configured transmission mode and configured power. The transmission mode is defined by the transmission duration, transmission duration and transmission offset. In the transmission duration, the PRS signal is transmitted by the PRS resource element of the PRS Orthogonal Frequency Division Multiplexing (OFDM) symbol within a defined subframe. In general, other data or reference signals are not transmitted during the PRS transmission duration to minimize interference from other data or reference signals. In addition, the transmission power (ie, Energy Per Resource Element (EPRE)) of each PRS resource element (RE) in the same cell is the same.

In the PRS design, a PRS signal from a cell is periodically transmitted in a preset pattern. The transmit power (EPRE) of each PRS RE is the same, and the PRS EPRE cannot generally be less than that of other broadcast data or reference signals, and the user equipment (UE) must detect the PRS in at least three cells to determine the location of the UE. Because it achieves the purpose of determining. However, the PRS signal must occupy a large amount of system resources. Otherwise, it is difficult to ensure the performance and accuracy of the positioning system, especially for positioning in indoor environments.

The conventional LTE system does not support multi-beam PRS transmission. Since support for beam forming and beam scanning is an important function of 5G NR system, the position reference signal design of 5G NR system must also support beam forming and beam scanning. Embodiments of the present application propose a method of transmitting a positioning reference signal used in an NR system and support multiple beams, thereby implementing terminal positioning in a system using an NR PRS.

An embodiment of the present application proposes a PRS transmission method in an NR system that implements PRS mapping and transmission by pre-setting PRS configuration information for a cell and/or an adjacent cell through a network.

Here, the PRS configuration information may include parameter information of a PRS block set, for example. Here, each of the PRS block sets includes one or more PRS blocks, and each of the PRS blocks includes a PRS signal that occupies one or more consecutive Orthogonal Frequency Division Multiplexing (OFDM) symbols.

Each PRS block set includes one or more PRS blocks, and each PRS block includes one or more consecutive OFDM symbols occupied by a PRS signal.

Of course, the PRS configuration information may also include other configuration information for realizing PRS transmission between the terminal and the network side in the NR system. Therefore, information contributing to PRS transmission can be used as PRS configuration information.

On the network side

The network side configures parameter information of a PRS block set for each cell, and transmits parameter information of a PRS block set of each cell or a plurality of adjacent cells to the terminal.

Each cell transmits a PRS signal according to the configured PRS block set parameter. The PRS block set parameter configuration includes time domain configuration information and frequency domain configuration information of a transmission PRS block set.

Here, the time domain configuration information of the transmission PRS block set is

PRS block set period and slot offset;

PRS block transmitted in the PRS block set or the number of PRS block identifiers or PRS blocks included in the PRS block set;

The location and quantity of OFDM symbols occupied by the PRS in each PRS block, or the location and quantity of slots occupied by the transmission PRS block; And

The number of slots per two adjacent PRS blocks, or the number of OFDM symbols per two adjacent PRS blocks

Includes.

The frequency domain configuration information of the transmission PRS block set includes mapping information of a PRS bandwidth, a frequency domain location, and PRS resource elements in a resource block RB.

The network side receives a positioning measurement value measured by the terminal and fed back by using the PRS signal, and positions the terminal on the basis of the positioning measurement value.

On the terminal side

The terminal side receives PRS block set parameter information of at least one cell and/or an adjacent cell transmitted from the network side.

For any cell, the UE will attempt to detect each PRS block in the set of PRS blocks transmitted in this cell. Each PRS block uses a different beamforming weight. That is, beam scanning is performed between different PRS blocks. Here, optionally, the UE may determine a detectable PRS block from the PRS block set according to the average Reference Signal Received Power (RSRP) of each PRS block.

For the PRS signal of the detectable PRS block, the UE measures the PRS signal and feeds back a positioning measurement value obtained based on the detectable PRS block to the network side. Since this detectable PRS block is determined by beam scanning, this positioning measure is the best positioning measure. Here, the positioning measurement value includes, for example, a reference signal time difference (RSTD) and a received power (RSRP) of the reference signal.

Optionally, the terminal may also feed back block index information of the PRS block corresponding to the positioning measurement value in the PRS block set.

Optionally, the terminal will also feed back the measurement time corresponding to the positioning measurement value.

Hereinafter, the PRS block and the PRS block set described in the embodiment of the present application will be specifically introduced.

PRS block (PRSB): One PRS block includes a PRS signal that occupies one or more consecutive OFDM (Orthogonal Frequency Division Multiplexing) symbols. The PRS signal of each PRS block is transmitted using the same beam. In one PRS block, the number of OFDM symbols occupied by the PRS can be configured. One or more PRS blocks may be configured in one slot. Also, one PRS block may occupy two or more slots.

PRSBS (PRS Block Set, PRS Block Set): One PRS block set includes one or more PRS blocks. The maximum number of PRS blocks in one PRS block set and the relative time domain position of each PRS block in the PRS block set may be predefined by a protocol. For example, the maximum quantity of PRS blocks included in the PRS block set is not less than the maximum quantity of SSB blocks in the Synchronization Signal Block (SSB) block set defined in the 3GPP specification.

That is, the maximum number of PRS blocks included in one PRS block set for a carrier frequency range of less than 3 GHz is 4 or more. For a carrier frequency range between 3GHz and 6GHz, the maximum number of PRS blocks included in one PRS block set is 8 or more. For a carrier frequency range greater than 6GHz, the number of PRS blocks included in the PRS block set is 64 or more.

In a specific implementation, the network side may configure the PRS block of the PRS block set used to transmit the PRS signal as needed. For example, in an implementation, the number of PRS blocks of the configured PRS block set is a synchronization signal (SS) of the configured SS/PBCH block set/Physical Broadcast Channel (PBCH) SS/PBCH of the block set. The beam direction of the PRS block of the configured PRS block set may correspond to the beam direction of the SS/PBCH block of the configured SS/PBCH block set In another implementation, the PRS beam width is SS/PBCH If the beam width is different from the beam width, the number of PRS blocks of the PRS block set may be less than or greater than the number of SS/PBCH blocks of the SS/PBCH block set The beam direction of the PRS block may also be different from the beam direction of the SS/PBCH block. Block set duration

1 provides an example of a possible PRS block set configuration. Each PRS block includes four consecutive OFDM symbols occupied by the PRS, and all of them perform PRS transmission in the same beam direction. Each PRS block set includes a total of 6 PRS blocks, each transmitted in 6 different beam directions. PRS blocks PRSB # 0, PRSB # 1 and PRSB # 2 are composed of consecutive OFDM symbols and there is no symbol gap between them. However, there is a gap between two OFDM symbols for downlink control channel transmission between PRSB #2 and PRSB #3.

The mapping pattern of the PRS block set is as shown in FIG. 2. The network side configures the transmission period and frequency position for the PRS block set, and maps and transmits the PRS block set based on this configuration.

The frequency domain configuration of the PRS resource represents the mapping between the PRS RE and the PRS RB, and represents the frequency domain location information and bandwidth of the PRS RB.

The time domain configuration of the PRS resource is introduced as follows.
